> Implement a scan works like the grpc streaming call that all returned results will be
passed to a ScanConsumer. The methods of the consumer will be called directly in the rpc framework
threads so it is not allowed to do time consuming work in the methods. So in general only
experts or the implementation of other methods in AsyncTable can call this method directly,
that's why I call it 'basic scan'.
